[Regression] Hibernation failure on dual core Athlon 64 (64-bit)

[Regression] Hibernation failure on dual core Athlon 64 (64-bit)

[Rafael J. Wysocki]

Hi Mathieu,

As reported at

http://bugzilla.kernel.org/show_bug.cgi?id=13903

one of my test systems suffers from a hibernation regression where the second
attempt to hibernate in a row makes it hang solid right before creating the
image.

Bisection turned up your commit 3f4a782b5ce2698b1870b5a7b573cd721d4fce33
([CPUFREQ] fix (utter) cpufreq_add_dev mess) as the first bad one.

Best,
Rafael

Tested (/me hates mailing list archives where you can't download raw messages
or at least raw patches) and it works.
 
Thanks a lot,
